What could happen if blood is drawn from a patient's arm too quickly?

It could cause bruising
It could lead to hemolysis
It could cause the vein to collapse
It could cause fainting

The correct answer is: It could cause the vein to collapse

Drawing blood from a patient's arm too quickly can lead to the potential for the vein to collapse. When blood is drawn rapidly, especially if significant negative pressure is applied, it can create turbulence within the vein. This rapid withdrawal can disrupt the flow of blood, resulting in a decrease in pressure in the vein itself. If the pressure decreases too quickly, it can cause the vein to collapse, making it more difficult to collect blood and potentially leading to complications such as delayed sampling or difficulty in accessing the vein again. Taking a more gradual approach can help maintain steady pressure within the vessel, ensuring a successful venipuncture and minimizing the risk of collapse.
